PowerSync

Sync Engine for Local-First & Offline-First Apps

PowerSync Overview

Our vision is that a local-first or offline-first app architecture should be easier for the developer than cloud-first, and give a better experience for the end-user — even when they're online.

PowerSync Philosophy

Quickstart / Overview

Quickstart Guide / Installation Overview

Connect a PowerSync Cloud instance to your backend database.

The core components of PowerSync are the service and client SDKs

Architecture Overview

PowerSync Service

Client Architecture

PowerSync Protocol

PowerSync uses the concept of "checkpoints" to ensure the data is consistent.

Consistency

PowerSync supports multiple client-side frameworks with official SDKs

Introduction

Self-host PowerSync in your own infrastructure (PowerSync Open Edition or PowerSync Enterprise Self-Hosted Edition).

Getting Started

Using Docker Compose to simplify your local development stack

Configure your backend database for PowerSync

Source Database Setup

Security & IP Filtering

Private Endpoints

Include the PowerSync Client SDK in your project

Client-Side Setup

You need to set up your client-side schema in your app project. This involves defining your schema in code using the PowerSync syntax.

Define your Schema

You need to instantiate the client-side PowerSync database — this is the core managed local SQLite database.

Instantiate PowerSync Database

The PowerSync 'backend connector' provides the connection between your application backend and the PowerSync client-slide managed SQLite database.

Integrate with your Backend

App Backend Setup

Your app backend needs to expose an API endpoint to write changes to your backend database that are received from the PowerSync client.

Writing Client Changes

Authentication Setup

Development Tokens

Firebase Auth

Auth0

Any authentication provider can be supported by generating custom JWTs for PowerSync.

Custom

Sync Rules

The simplest Sync Rules are for "global" data — synced to all users. 

Global Data

Organize Data Into Buckets

Parameter Queries

Data Queries

PowerSync's Sync Rules use the [SQLite type system](https://www.sqlite.org/datatype3.html).

Types

On the client, PowerSync only supports a single primary key column called `id`, of type `text`.

Client ID

Operators and functions can be used to transform columns/fields before being synced to a client.

Operators and Functions

Schemas and Connections

For simplicity, we recommend using only lower case identifiers for all table/collection and column/field names used in PowerSync. If you need to use a different case, continue reading.

Case Sensitivity

A group of rows/documents, from one or more tables/collections.

Glossary

Guide: Many-to-Many and Join Tables

This section covers use cases that will arise throughout the lifetime of your application as you add new features, refactor tech debt into oblivion, and upgrade dependencies.

Lifecycle / Maintenance

Implementing Schema Changes

The general approach is that for transient errors (e.g. server or database unavailable), the changes are kept in the client-side upload queue, and retried at 5 second intervals, keeping the original order. In the future it will be possible to control the retry behavior.

Handling Write / Validation Errors

Upgrading the Client SDK

Postgres Maintenance

[Buckets](/usage/sync-rules/organize-data-into-buckets) store data as a history of changes, not only the current state.

Compacting Buckets

Learn how to use PowerSync in common use cases

Use Case Examples

Syncing large attachments/files directly using PowerSync is not recommended.

Attachments / Files

Run PowerSync operations while your app is inactive or in the background

Background Syncing

While PowerSync does not use [CRDTs](https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type) directly as part of its sync or conflict resolution process, CRDT data (from a library such as [Yjs](https://github.com/yjs/yjs) or y-crdt) may be persisted and synced using PowerSync.

CRDTs

PowerSync is fully compatible with more advanced Postgres types.

Custom Types, Arrays and JSON

Data Encryption

Client-side full-text search (FTS) is available using the [SQLite FTS5 extension](https://www.sqlite.org/fts5.html).

Full-Text Search

Infinite scrolling is a software design technique that loads content continuously as the user scrolls down the page/screen.

Infinite Scrolling

Some use cases require data persistence before the user has registered or signed in.

Local-only Usage

Custom types, arrays and [PostGIS](https://postgis.net/) are frequently presented together since geospatial data is often complex and multidimensional.

PostGIS

In some scenarios, you may want to sync tables using different priorities. For example, you may want to sync a subset of all tables first to log a user in as fast as possible, then sync the remaining tables in the background.

Prioritized Sync

Use Custom Write Checkpoints to handle asynchronous data uploads, as in chained data pipelines.
